Device (1) for securing portable steps in building and civil engineering works, which enhances the safety thereof, minimizing the risk of falling. This device is affixed to the longitudinal members (4) or crossmembers (5) of the steps and to the support article (3), using clips. In order to affix the clips securely, the device (1) rotates and moves the clips in the three spatial axes (X,Y,Z). In order for it to be possible to correctly affix the device to different articles, be these of different form or material, there are likewise different support elements (28). The device is removable and more than one thereof can be used on the same steps. This device secures portable steps to articles such as floor slabs, sloping roofs, pillars, posts or trees. |

1. Removable safety device of the type to be incorporated into the longitudinal members or cross-members of portable steps for securing to different objects, by tightening a number of clips by having a first structure configured for moving and rotating the fastening clips relative to the X axis, the X axis being defined by the virtual line formed between the jaws which are secured by pressing the longitudinal members or cross-members of the portable steps, as it is provided with a second structure configured for moving and rotating the clips relative to the Z axis, the Z axis being defined as a virtual line perpendicular to the X axis, and the translational and rotational movement relative to the X axis of the clips being provided with an X clamp, the X clamp being oriented along the X axis and having a clearance fit relative to the tube, enabling its translation and rotation relative to the X axis, The, the X clamp having a conventional fastener, the translational and rotational movement relative to the Z axis of the clips is provided with a Z clamp, the Z clamp being oriented along the Z axis and comprising a clearance fit relative to the Z tube, enabling its translation and rotation relative to the Z axis, the Z clamp being provided with a conventional fastener, the translation and rotation on the X and Z axes thereby enabling the safety device to direct and place the clips in the best position in relation to the support article. |
